Re: [iPhone] Convert date string to a NSDate object

Just found the answer from Date Formatting Prog. Guide.. Format Strings section.. NSDateFormatter *inputFormatter = [[NSDateFormatter alloc] init]; [inputFormatter setDateFormat:@"-MM-dd'T'HH:mm:ss'Z'"]; NSDate *formatterDate = [inputFormatter dateFromString:@ "2010-01-08T08:09:20Z"]; Thank y

Hiding the Window Content View

When the content view of a window has setHidden:YES called on it the result is a Title Bar, Size Control and a "body" (for lack of a better term). Is it possible to get rid of this "body" leaving just the Title Bar and Size Control. The effect would be that when dragging the Title Bar the

Correct. Nothing happens until the window is 'flushed' (which normally happens in the event loop). It is one of the joys of programming on the Mac (compared to Windows). Paul Sanders - Original Message - From: "David Blanton" To: "cocoa-dev List" Sent: Friday, January 08, 2010 8:38

Re: Hiding the Window Content View

Well, there is no flicker issue to worry about, but to optimise for this case (i.e. save some CPU cycles), have the view you are drawing into return YES from its isOpaque method. Cocoa will then assume that this view completely obliterates whatever lies behind it (including the content view).
